Is the following statement true or false, why?
1. Let m[1]...m[p] be the LCS of A[1]...A[i] and B[1]..B[j]. If A[i] is not equal to B[j], is m[1]...m[p-1] a common subsequence of A[1]...A[i-1] and B[1]...B[j-1]?
2. Let m[1]...m[p] be the LCS of A[1]...A[i] and B[1]..B[j]. If A[i] is not equal to B[j], is m[1]...m[p-1] a longest common subsequence of A[1]...A[i-1] and B[1]...B[j-1]?
1. True
Explanation: If A[i] != B[j], this means that the common subsequence must lie before indices i and j.
Hence, m[1]...m[p-1] a common subsequence of A[1]...A[i-1] and B[1]...B[j-1].
2. False

2. (40 pts) Let A, B, and C be three strings each n characters long. We want to compute the longest subsequence that is common to all three strings. (a) Let us first consider the following greedy algorithm for this problem. Find the longest common subsequence between any pair of strings, namely, LCS(A, B) LCS(B, C), LCS(A, C). Then, find the longest common subsequence between this LCS and the 3rd string. That is, supposing that the longest common pair wise...

Question 2 (2.5 points) Longest common subsequence Consider the procedure to determine the length of the longest common subsequence, LCS- LENGTH(X, Y). It solves the LCS problem in a bottom-up manner, by filling out a 2-D tabular LCS-LENGTH(X, Y) m = X.length 2. n-Y.length 3. let cO.m, 0n] be a new array 4, for i = 0 to m for/ = 0 to n else if ATY ci,ci ,j-1 +1 10 else 12. return clm, n] For example, X (B,...

I need this using C++.
In this project, you will implement the dynamic programming-based solution to find the longest common subsequence (LCS) of two sequences. Your inputs will be the two sequences (as Strings) and the outputs are the longest common subsequence (printed as a String) and the final matrix (printed as a two-dimensional array) depicting the length of the longest common subsequences (as shown in the slides) for all possible subsequences of the two input sequences. The two input...
Create a C++ Header Function with DYNAMIC programing with the following details: longest common subsequence input: a string a of length m and a string b of length n output: the longest string ssuch that s is a subsequence of both a and b; in the case of ties, use the substring that comes first alphabetically The dynamic programming algorithm for subsequences is similar to the one for substrings. Both involve a 2D array of strings, base cases, and a...
